But it will-appearas the Idescription r v progresses that the number of combinations may 'bemore or less than one hundred eight? two and that :itsemployment in connection with two fontsh of matricesis not the'only use iforthe improvement Also, it. usedin connection with two fonts of (matrices, the" secondfont :neednot ff'ollo-wthe first as herein illust-rated, but the itWlQ-fOlltS may alter- J nate' character for, character .across 'tlie lengthofthe distributor barvandmagazine; v 1

:Broadlystated,the principle ofxmy im provementresides in re-employing thereguzlar series of distributii1g combinations on, the bar by"n'uaking;them narrower than'here' tofore intheinstance of their first use and p. or

comparatively wider i in theiinstance; of their second usefgTheir first use is in connection with f-onts er inatrices having narrow dis? 7 tributing teeth and their reeemployment is inconnection I with matricesihaving comparatiyely wider distributing teeth; The wider teeth on the-matricesof theisecondfont will V bridgethe'bar combinations from which the first font is distributed and therefore thejsec+ 7 0nd font will be carried across the first and;

narrower-seriesof b'ar combinations andwi'll a not bedisengaged from the bar until they reach-the re -employed but wider bar combinations from which they are intended to Y be distributed; a

, being of a widthjust sufiicienttoaccommodate the web X (Fig; 6) on which the matrix teeth are ;,usually out. But in their reemployment beginning with" channel No.

1 06,combinationNoffi tsecond my the b'ar r 1 binations which are the sameas those simi-' combinations are as wide the associated matrix, plus a reasonable clearance, and' the matrix teeth are the full width of the illlClZ- ness of the matrix. Taking this second in matrix as an example it will be noted that it bears the same combination as the first i (channel No. 6). The combinations .numbered from 1 to 5 as well as others there? beyond are not re-employed for the reason that the matrices bearing these combmations have fewer than three retained teeth and this number is considered essential to w-itlr stand the tendency of the teeth to Wear as the matrices travel across a long distributor bar. This explains the omission of certain nun'ibers in the second series of combination nun'ibers, those retained representing. comlarly numbered in the case of their first em-. ployi'nent. It will be noted that some of the re-employed con'ibinations beginning with the'second m and including the w, fi, fl, if, iii,-fli, quad, and-others beyond, break into the-first series of combinationsv ending with No. 124. This is because these.interrupting characters are thick and it isconsidered expedient to reserve as many as possible of the regular or first series of combinations .2 and lli'flClClltlOl'I 27 combinations employing less than three matrix ;teeth have. been omitted from the drawings. With a single exception, the 40 combinations omitted at the end of Fig.2 are desirable combinations in the sense thatthey employ three or more matrix teeth. 3

In addition to the double use of'the dis-' tributing combinations as above explained,

it is also possible to use the same combination three times. F or example, in the first S, second F andsecond W channels are shown matrices bearing the same combination oflst, 3rd and 7th teeth. ,The F will bridge thefS combination as before explained and by shortening its 3rd tooth (Figs. 2 and 4) on its leading side it will clear an added rib3 cabove its own channel.

This added rib will be engaged by the 1st tooth on the l/V matrix and by shortening this 1st tooth on the following side of the matrix,'the W matrix will be released into its channel at the proper time. In addition a third series ofmatrifces still thicker than the second serles would bridge the two series of bar combinations and the bar could be extended accordingly. The invention would also be useful in connection with an ordinary 90-character font of matrices as a means of increasing the size and strength of the matrix teeth; i. e., the. number of teeth could be fewerand larger without increasing the size of the matrix, and the same combinations used in distributing the lower-case matrices could be. re-employed for distributing the capital letters. Referring to the drawings in regard to my improved construction for ad-istributor bar, it will be noted that the upper, or first, rib is broken up intoa great many/parts, one part for everyother distributing combination; the second rib has only half as many breaks as the first; the third only half as many as the sccondj the fourth half as many as the third; the fifth, half as many as the fourth; the sixth half as many as the fifth, and the seventh, halfas many asthe sixth. Since the combinations must be accurately and smoothly cut or chipped one at aft-ime from the ribs in the method heretofore employed, it is apparent that if the more numerous combinationsin the first four ribs can be produced by a stamping process or bya milling processseveral at a time,

considerable economy and increased accuracy would result. It is with these objects in view that I provide the laminated construction, shown in Fig. 9. The three lower ribs (more or less) are formed as usual'on a solid barA. Since theselowerribs have but few, widely separated, combinations, this part of the bar may be constructed in the usual manner or by any improved method made possible by the omission of the upper ribs. This provides asufliciently strong and stiff bar to which the laminations B may be secured by mean of aseries of bolts G or otherwise. Since the, four laminations on one side of the bar are the same as those on the other side except for the direction in which they are bent at their lower edges, it follows that ina stamping operation; the sametools may be employed for both sides; and in a milling-operation many laminations may be milled at one time. Also, in case of wear such as occurs especially at; the lower case end of .the bar, certain parts ofthe barmay be renewed as. occasion requires. The laminations may be clamped between ,side plates B A modified form of laminated bar illus- V Y trated inFig '11. In this form the several lower ribs are formed on a solid bar D of sufiicient depth to receive the threadedend of aseries of .boltsE; Th'e'laminations F are clamped-between the ribbed bar D and a plain bari G, beingperforated to receive the bol-tsE. c

Having thus described the advantages and construction of invention, what, I claim as new and desire to secure by Letters Patent, is: V

. ,1. A single typographical distributing bar having distributing combinations in duplicate, the first of each duplicated combination being narrow and the. duplication thereof combinations may be incapable of release i iot'relatively Wider, for the purpose specified.

I 2. A" distributing bar for typographical p matrices having'thereon afir st series of nar- H 10 row distributing combinations followed by a second series of relatively Wider combinations, in order that the matrices capable of being released from said .secondseries from said first series of combinations.

3. In combination, a distributor bar having a first series of narrow distributingcombinations for distributing afirst. set ofmatriceshaving correspondingly narrow distributing combinations a. second set of mat- V i rices having distributing combinations of 1 a Width sufiicien-t to bridge the combinations idth. for releasing a matrix having a dis- ,tributing combination of limited Width, and

a relatively wider duplicate of said matrixreleasing combination on said bar for releasseries of narrow matrix-releasing combina-' mg a matrix having a distributing combination of corresponding Width.

v5. In a matrix-distributing bar, a first tions and a second series of Wide matrixreleasing combinations, said first series of combinations. being capable of releasing only matrices having narrow distributing teeth and said sec-ondseries of combinations being capable of releasing matrices having Wide I distributing teeth I '6. In combination, a distributing bar hav ing a matrix-releasing combination cut transversely from "a series of longitudinal" ribs, matrices, having distributing teeth equal in number to the ribs from; which said'releasing combination-is out, apair of I channels nto Which said matrices .arefre leased,'and means Whereby the same combi-' nation of matrix tBth'Wlll release certain matrices into thefirst onejo t'rsaidpair of, channels and others thereof into the other channel, said means comprising a tooth 3"" on said bar, a tooth shortened from one side of the matrices destined for the first'of said-f advance thereof, and a tooth shortened from the opposite side-of the matrices destined channels in order, to clear said bartooth in.
